Hi,

Well, technically these would be separate vulnerabilities, wouldn't you say?
Could you perhaps share a bit more information about which headers work well in circumventing which AV products?

get the new updates at,
http://www.geocities.com/visitbipin/crc.html

strangely, after modifying other general purpose bit
flag in the zip header like,compression method,last
mod file time,last mod file date,file name
length,extra field length... [NOT: compressed size, uncompressed size which was
pointed out by iDEFENSE before]

strangely i found some other AV pron to the BUG.
